High impact information on Taraxacum

• Taraxalisin -- a serine proteinase from dandelion Taraxacum officinale Webb s.l [1].
• Effects of taraxacum mongolicum on the bioavailability and disposition of ciprofloxacin in rats [2].
• HPLC analysis of geometrical isomers of lutein epoxide isolated from dandelion (Taraxacum officinale F. Weber ex Wiggers) [3].
• Two new compounds, taraxafolide (1) and (+)-taraxafolin-B (2) together with eighteen known compounds, which include one sesquiterpene, thirteen benzenoids, two indole alkaloids, one pyridine derivative and steroid mixtures were isolated and characterized from the fresh roots of Taraxacum formosanum [4].
• All were tested with SL mix 0.1% petrolatum (pet.) and diethyl ether extracts from Taraxacum officinale (dandelion) 0.1 and 3.0% pet. and from Stellaria media (common chickweed) 0.1 and 3% pet [5].

Anatomical context of Taraxacum

• Taraxacum officinale restores inhibition of nitric oxide production by cadmium in mouse peritoneal macrophages [6].
• Chemical examination of the MeOH extract of the root of Taraxacum officinale, which exhibited inhibitory activity on the formation of leukotriene B4 from activated human neutrophils, has resulted in the isolation of 14-O-beta-D-glucosyl-11,13-dihydro-taraxinic acid (1) and 14-O-beta-D-glucosyl-taraxinic acid (2) [7].

Associations of Taraxacum with chemical compounds

• Purple-coloured dandelion (Taraxacum officinale) callus cultures producing anthocyanin pigments were established on a cytokinin-rich medium under the light [8].
• Cd uptake was maximal in Taraxacum officinale at 15.4 mg/kg (Superfund site) [9].
• A new guaianolide, taraxacin (1), and a known sesquiterpene ketolactone (2) have been isolated from an ethyl acetate-soluble part of a methanolic extract of Taraxacum wallichii [10].
